Abstract
A flame resistant composition comprises (a) a polymer; (b) a synergistic mixture comprising(i) from about 0.6 to about 3 percent of a non-halogenated flame retardant compound; and (ii) at least about 0.06 percent of a compatible additive; wherein said percentages are based on weight percent of (a) plus (b), wherein (a) plus (b) equals 100 percent. A method of rendering a polymer flame resistant comprises compounding said polymer with a synergistic mixture comprising (i) from about 0.6 to about 3 percent of a non-halogenated flame retardant compound; and (ii) at least about 0.06 percent of a compatible additive; wherein the percentages are based on weight percent of polymer plus the synergistic mixture, and wherein polymer plus synergistic mixture equals 100 percent.
